CH_SW01ESTUARINE MANGROVE FORESTSCIENTIFIC NAME River Mangrove (Aegiceras corniculatum) - GreyMangrove (Avicennia marina subsp. australasica) Riparian Estuarine ForestSTATEWIDE CLASS Saline Wetlands – Mangroves (Keith 2006)CH_SW01PLANT COMMUNITY TYPE Grey Mangrove – River Mangrove lowopen or closed forest or shrubland of intertidal flats, NSW North CoastBioregion and the South Eastern Queensland Bioregion (NSW700-686)DescriptionLow to mid-high open to closed forest or shrubland occurring on the margins of coastal estuaries on mudflatsthat are exposed to tidal inundation. The canopy is usually dominated by Grey Mangrove (Avicennia marina subsp.australasica) which often forms a simple, monospecific stand, although in brackish waters the River Mangrove(Aegiceras corniculatum) is more frequent (recorded at Moonee estuary, Newports Creek and Bonville Creek).The shrub and ground layers are usually absent, although a few scattered herbs such as Creeping Brookweed(Samolus repens) and Samphire (Sarcocornia quinqueflora) may be present.Occurrences of less common mangrove species have been recorded in the area. Spider Mangrove (Rhizophorastylosa) reaches its southern limit in the study area at the Corindi River estuary and Milky Mangrove (Excoecariaagallocha) has recorded at Arrawarra foreshore and Bongil Bongil National Park.Occurs on the margins of coastal estuaries on mudflats that are exposed to tidal inundation.Page 382Vegetation Mapping of the Coffs Harbour Local Government Area
